摘要

数字版权管理是网络音乐发行中的一个关键问题。授权模型是DRM中的一个重要概念，因为任何做出授权决策的实现都会使用它，例如，当试图决定用户是否可以对音乐专辑或曲目执行操作时。本文提出了MPEG-21 REL标准定义的授权模型的实现。它是目前唯一一个作为参考软件提出的。还介绍了构成授权模型的不同元素的数据类型的定义。

Use of rights expression languages for protecting multimedia information

Digital rights management is a key issue in music distribution throughout the Web. The authorization model is an important concept in DRM because it is used by any implementation which makes an authorization decision, for example when trying to decide if a user can exercise an action over a music album or a track. We present in this paper an implementation for the authorization model defined by the MPEG-21 REL standard. It is currently the only one that has been presented as reference software. The definitions of the data types for the different elements that form the authorization model are presented too.
